That's the one I have currently, the MLS teams are set to overwrite over the other Latin American teams.
Tested with Chicago Fire, selected "choose who to import over" and the one it would have selected by default was Medellin, who I had imported earlier into the other Latin American teams. I tried to see what would happen if I selected one of the PLA teams to import over instead, and while Chicago Fire looked fine and had what looked to be a correct squad of players, Medellin reverted back to a squad full of free agents/created players.
Yeah man. This is the most complete and only MLS out there that I could find. There's a creation thread but nobody has done it yet.
The Libertadores teams, I organized to work with that version of MLS...of which he made to be comptabile with the Liga MX that was build on the PLA league...
I started a ML with both the Liga MX, and MLS, and found 20 MX teams in the copa libertadores, that's when I changed it, I figured I would have to choose. I chose MLS because it's been the retirement home of the greats for a while now. And it's the fastest growing league in the world. Though quality still has much to be desired.
So I kept the 7 best MX Teams and replaced them...
I think Cristiano chose a different set of teams for his preference...
I'll tell you how you can do it though...
Save your Roster the way you want it...export it to a USB, the whole option file.
Import all the teams you like...onto the default rosters...
Then base copy the players of the team you like onto the new team of your choices default base players.
Export the new base copied team.
Go and delete your option file, and reimport the new option file
